SONY HBD-N7100W OPTICAL OUT OF ORDER

Hi,
 I own a Sony Blu-ray player, model HBD-N7100W, whose original optical unit was defective.
I recently replaced this part with a new, compliant optical unit, but when I restart it, the device asks me for an update file (BUData.txt file) necessary to initialize the new laser.
I would like to know if someone could generate this file for me. I can provide the data matrix of the new optical unit.
I thank you in advance for your help and remain available for any further information.
 
Regards,
 
Sylvain
